Chapter 7 Absolute Reset and Absolute Battery
7.1 Absolute Reset
The controller for Simple Absolute Type retains the encoder position information with the
battery backup. Also, connecting the battery-less absolute type controller to an actuator
enables to retain the encoder position information without any battery. For those types, it is not
necessary to have a home-return operation in every startup.
To retain the encoder position information, it is necessary to register (absolute reset) the home
position.
It can be checked on the status LEDs for the driver whether the absolute reset is necessary.
Have an absolute reset completed if the status LEDs for the driver shows the absolute reset is
incomplete.
(Note) For battery-less absolute type, conduct an absolute reset after motor replacement.
(Note) There is no battery-less absolute type and simple absolute type in the DC brushless
motor type.
[1] Status LEDs for Driver
Driver status (condition) and absolute status can be displayed for each axis to be connected.
There is no absolute status display for the incremental type and battery-less absolute type.
